A cleansing treatment with a soap Solution at 160o F. for 40 minutes follows, and the goods are then washed well and acidulated.

I claim: I

1. The process of treating Silk comprising dyeing it in a continuously boiling liquor With a direct dye, and fixing the dye upon the silk at an elevated temperature.

2. The process of treating silk comprising dyeing it in a continuously boiling liquor With a direct dye and then mordanting the dye With tannic acid at about 1600 F.

3. The process ot treating silk comprising dyeing it in a continuously boiling acidulated gum soap liquorWitli a direct dye, adding tannic acid to the same liquor and treating the silk therein at about 1600 F.

4. The process of treating silk comprising dyeing it in a continuously boiling liquor with a direct dye, mordanting the dye at a high temperature and diazotizing the dye.

5. The process of treating silk comprising dyeing it in a continuously boiling liquor With ardirect dye, mordanting the dye at a high temperature and diazotizing and developing the dye.

6. The process of treating silk comprising dyeing it in a continuously boiling liquor With a direct dye, mordanting the dye at a high temperature, diazotizing and developing the dye and treating with a hot soap solution.

7. The process of treating silk comprising dyeing it in a gum soap liquor containing a direct dye, treating it With tannic acid at 1600 F., Washing it, treating it with tartar leinetic, Washing it, diazotizing the dye,

Washing, developing With sodium carbonate, cleansing With a soap solution, and Washing and acidulating.

8. The process of treating silk comprising dyeing it in a continuously boiling liquor With a direct dye, fixing the dye upon the silk at an elevated temperature and treating the silk With a hot soap solution.

9. rFhe process of treating silk piece goods comprising dyeing them in a continuously boiling liquor with a direct dye, and fixing the dye upon the silk at an elevated temper-y ature.

`10. The process lof treating silk piece goods comprising dyeing them in a continuously boiling liquor with a direct dye and then mordanting the dye With tannic acid at about 1600 F.
